PC Instant Replay not working properly anymore

Instant replay has worked normally until last night. When I pause game now, and go to instant replay, i get the replay, but my "F" keys do not work so I cannot stop the replay, or move frontwards and backwards. The entire replay occurs and once it is finished, then the F12 key activates, but by then it's too late.

I did add a mod the night before and thought that might be the cause, even though the mod didn't actually become active. I removed it, but no change. I even reset my computer to last week, but the instant replay still doesn't work.

I'm not even close to being good enough to play without playbacks, so this stinks.

Not sure why the F keys arent working sorry, but ive noticed that my controller left and right actually forwards and rewinds the replays as well as the F keys.
Maybe you could try that as a workaround.
